Measurement Surface Ultra Hard Sapphire Prism Other manufacturers compromise From the pictures below one can see that other manufacturers have to make a compromise with the depth and angle of the sample well. Since these manufacturers use one sample well and cover design for all temperature applications, they end up with a sample well that is too narrow and deep. The deep sample well makes cleaning needlessly hard at ambient temperature while failing to provide ideal temperature control when the sample and air temperature are more than 10°C from the desired measurement temperature. Other Brands have Covers Without a Temperature Control Function Some manufacturers use glass or YAG ( Yttrium-Aluminum-Garnet) prisms. These prisms are softer than synthetic sapphire Evaporation can be Sample a problem due to large and have slower temperature transfer coefficients. Deep sample sample cover volume well design or irregular contact around Don’t worry, you can clean the Rudolph prism with regular creates difficult the sample perimeter paper towels, no special cleaning paper is required. to clean areas 30 C air Ultra Flat Prism temperature TEMPERATURE GRADIENT Temperature Controlled Prism Surface 20 C prism temperature Competitor 1: Deep Sample well with prism only temperature control Easy to clean prism – No matter how good the refractometer is, the results will only be right if the prism is clean. Rudolph’s flat prism sample well interface design makes cleaning easy, even with sticky syrups. The flat low profile sample well with a sample volume of less than 1ml is easily cleaned by wiping with a common paper towel. A single cleaning surface with a scratch-proof synthetic sapphire prism makes the J157 a popular choice for high throughput laboratories. Standard Prism Competitor 2: Difficult to clean prism sample well interface The flat open sample area has no corners to trap even sticky materials and is resistant to almost all solvents including Acetone, Toluene and similar organics. Choose the Hastelloy option for HFl and HCl acids.

Your instrument’s interface can be customized to meet the information your application and environment demand whether you choose our full featured interface or our Load-and-Go™ display interface. The J157 Plus Series offer laboratory flexibility with industrial strength and simplicity making this model series at home on the laboratory bench or on the factory floor. Full Display with Smart Measure™ Load - and - Go™ Display Trend Analysis™ Display In a modern factory, the most precious commodity is time. When a process starts to move outside its limits people want to know FAST. They want to correct the problem, preferably while it’s still small and before a product goes out of specification. The Rudolph live reading and Trend Analysis™ feature allows users to easily and quickly see how a process is going and catch minor deviations before they become major ones. Even in the most tightly controlled manufacturing environments, things do occasionally go out of specification. When an out of specification condition happens, material has to be quickly identified and decisions made as to what to do with the product. Long term data collection is a part of any good process. Knowing when and where the out of specification condition happened is equally as important. Rudolph Trend Analysis™ software quickly shows a supervisor the process history and where the problem occurred.

Contact (CP) Temperature Controlled Sample Presser Optional Contact Presser (CP Presser) The J157 Plus Series are available with an optional Temperature Controlled Sample Presser that Sample Shallow touches the sample. Compared with the standard sample temperature controlled cover, the optional wel (CP) Contact Presser reduces the empty volume of the Temperature measurement area thereby decreasing evaporation controlled prism and at the same time helping to evenly spread semi solid materials over the measurement prism. This feature offers improved Environmental Cover (EC) performance on many samples such as With No Temperature Control PET and Glycerine. (EC) Environmental Cover is great for applications where a micro environment is needed but Sample Shallow sample samples are measured near room well temperature where heating and cooling from above the sample may Temperature not be needed. controlled prism Sugar Milling, Refining, Processing Pour Through Solutions Pour through refractometers are designed for measuring • Cane sugar milling and refining cane or beet juice in a sugar mill. This design has two important • Beet sugar milling and refining benefits: cleaning becomes part of the sample loading process • Invert sugar and measurement time is reduced because one sample is • Liquid sugar poured in after another making the design attractive for • Confectionery sugar seasonal operators. The small funnel design forces improved • Molasses sample flushing by increasing the number of sample pours for • Brown sugar the same amount of sample.
